2. Clean the exhaust filter housing inside manually as good as possible (for
example, with clean dry cloth).
3. Change the oil filter but leave the existing exhaust filters inside the housing.
4. Fill the pump with the correct amount of new synthetic oil.
5. Run the pump for about 2 hours, then stop it. Drain the oil, clean inside as
before and change the oil filter again.
6. Refill with new oil and change the exhaust filters. Repeat this procedure until
the oil remains clean (sight glass).
7.6.4. Cleaning radiator, motor fan guard and pump
Radiator, motor fan guard and pump must be kept clean. This can be done using
compressed air and a dry cloth. Be careful not to damage the oil cooler (if
applicable) by cleaning with compressed air or by exerting excessive pressure
with the cloth.
Do not use fluids or substances other than those indicated.
7.6.5.
Cleaning the intake filter (optional) element
1. Remove the intake filter element from the housing.
2. Clean the intake filter element in one of the following ways:
▪ Hand washing:
Soak and agitate element in a warm water and mild detergent solution.
Allow adequate time for the element to air dry (24 hours minimum). Do not
install a damp element. This will cause higher initial pressure loss and
rapid dirt loading.
▪ Compressed air cleaning:
Using approximately 7 bar(e) (100 psi(g) or 5.25 Torr(e)), direct air flow at
inside of element towards pleats. Blow off the outside of the element
directing the air flow down to avoid embedding dirt in the media. Blow off
the inside again to remove any dirt that might be on the clean side of the
element.
▪ Vacuum cleaning:
Point the vacuum cleaner to the dirty side (outside of element) only, using
a vacuum of approximately 100 mbar(a) (75 Torr(a)). A crevice tool is
recommended.
▪ Hand cleaning:
Hold element down with one hand and move other hand across the fins in
a strumming motion. This action will dislodge most of the dirt.
3. The element is ready to be reused.
7.6.6. Replacing V-belts
GVS 470A
